To all whom it may concern:

Be it known that I, EDMUND GALE Jnwn'rr, a citizen of the United States, residing at Bellingham, in the county or" What-comand State of Washington, and useful Improvements in Apparatus for Distilling Wood; andl do declare the following to be a full, clear, and sheet description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improved ap aratus'for distilling wood for. the purpose o1? obtaining alcohol, tar, turpentine, and other products thereforni; and it consists in the construction, combination, and arran ement of de- Vices hereinafter described an claimed. 1

In theaccompanying drawings, F1 re 1 1S a vertical sectional view of a woodistilling apparatus embodying myimprovements, and Fig. 2 is a horizontal sectional view of the same. 7

The furnace 1 is here shown as of circular form and is provided with a relatively narrow grate 2, which extends diametrically across the same, and with a pair of shorter grates 3 at opposite sides of the furnace and arranged'mt right angles to the rate 2. 'Un der each gr ate is an ash-pit, an in each ashpit is located an air-pipe 4, to which air under asuitable degree of compression is supplied, and each of said air-pipes is provided with upwardly-extending air-dischar ing nozzles 5, which are opposite, the spaces etween certain of-the bars of the grates and are disposed in mixing-pipes 6, to which gas is supplied by gas-pipes 7. The air from the pipes 4 corniningles'with the gas in the mixing tubes or ipes and serves to greatly romote the combustion of the gas, as wil e readily understood. l/Vithin the furnace are retorts-8, which may be of any suitable number. Four of the retorts are here shown in the furnace disposed in two groups on opposite sides of the grate 2, the said groups oi retorts being spaced and separated by the said grate 2. The shorter grates 3 partially enter the spaces between the retorts of the several roups. Each of the said retorts has its lower portion disposed in a shield 99, with which the furnace is provided, Said shields are here shown as constructed of fire-brick. Each of the said shields forms a chamber 10 for the reception of the lower end of one of the retorts, and each of said retorts has a funnel- Specification of Letters Patent. 7 Application filed JunaZQ. 1905.

shaped bottom 11, from which leads a conduit 12 for the products of distillation. The upper portion of each of the retorts is here shown as protected from thda flames in the furnace by a metallic shield 1'3, which rests on the fireebrick shield 91 A stopper 15, Fi 2, which is made of asbestos, is between sac of the rctorts and the fire-brick shield 9, as shown. Each of the retorts is made of metal and is here shown as cylindrical inform. The

upper end of each retort asses throu ham 1 opening in the top of the mace and is provided with a cover 17, whichis here shown as of substantially conical form. The diameter of the covers 17 is greater than that of the retort, so that the outer ed es of the covers pro- Lect beyond the outer si es of the retorts and 'e in trencheslS, with which the top of the furnace is provided. Clay or other suitable plastic material ora readily-fusible metal is laced in the said trenches and serves to efectually seal the covers of-the furnace to prevent the escape of the products of distillation therefrom, as will be readily understood. From the top or cover of each retort is suspended a crate 19, which extends nearly to the bottom of the retort. The said crate comprises outer and inner vertical bars 2021, radially-disposed bars 22, which connect said outer and inner bars, hoop-bars 23, secured to the inner sides of the vertical bars 20, and the smaller hoop-bars 24, surrounding and secured to the outer sides of the vertical bars 21. These hoop-bars serve as braces for the crates, and are nioved with the crates when the are lifted out for rechargin The radia bars 22 are inclined andisposed in downwardly-converging planes and serve to support -annular bars 26, which-divide the crate into vertical sections and which'serve to support the wood that is placed upright in the said sections and is introduced into the said. sections by being passed through the spaces between the outer bars 20: By having the circular hoop-bars 24 detachable from the bars 21, so that the T may be raised or lowered, the placing of the wood in the sections of the crateis greatlyfacilitated,as will be understood. The inner verticalbars 21 of the crates forma central vertical shaft 27.

is a funnel-shaped metallic bottom 28,-having a central opening through which the shaft 27 extends and which serves to convey the products of distillation from the several sec- I0 5 Under the bottom of each section of the crate tions of the crate to the said shaft so that the the top 17 and is provided with a plurelity of radially-disposed inclined discharge-pipes 38, the latter being disposed in the upper end'cf the respective sections of the crate and the function of which is to enable Water to be dis charged into the crates for the purpose of spraying the contents thereof. Also in each of the retort-tops17 isa pipe 31 .tor the reeeption of a thermometer. The pipes 33 serve as spray-' ipes for the upper retorts.

v It will e understood thatwhen the top of one of the retortsis raised or lowered the crate which is secured thereto and depends therefrom will be also raised and lowered, and in practice I employ suitable cranes or other devices for raising and lowering thetops and the crates, so that the crates may be removed from the retorts for; the purpose of charging them and of removing the charcoal therefrom.

Hence the charging of the retorts is very greatly facilitated.

From. th fore oing description, taken in connection with t e accompanying drawings, the construction and operation of the inven+ tion'will be readily understood without .re-

' further explanation.

- .1 changes in the forimproportion,

and the in" or details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described my invention, what 1 clsiin asnew, and desire to secure by Letters Patent, is-

- 1 In a Wood distilling sgparatus, a'series of retorts, a furnace exten mg betweenvthe retorts crstes in the retorts, said orstes comprising radial-bars, snnular oars secured to said radial here, a wateripe and leterell'y".

supported upon the radial bars, funnelshaped metal bottoms, a- Water-pipe, and spray-pipes connected thereto, substantially as described.

In testimony whereof I have hereunto set my hand in. presence of two subscribingwit nesses.
